Somehow I managed to lose the o-ring on my Octane 45 piston. This is one of those feats I have a real penchant for...especially since it hasn't been any where besides the safe and my desk. I ordered up a couple Silencerco replacements. So I'm covered for now. My question is, what are the dimensions of the Viton o-ring and is there a cheaper bulk option? I don't plan on losing another one. But then again, I didn't plan on losing the first. Plus I look forward to wearing them out the old fashioned way in the near future.
